OnEventWatch

OnEventWatch tracks the performance of OnEvent handlers, showing how much time they take per frame. It helps identify slow or frequent events, aiding in diagnosing UI and addon performance issues.

Installation

Manual Installation Only

Download this zip: OnEventWatch_1_2.zip

Usage

To start profiling: Type /onevent in the chat window.
First run: The addon will scan all frames and note those with an OnEvent handler. It then wraps these handlers with timers (debugprofilestart() and debugprofilestop()) to measure execution time.
Subsequent runs: /onevent toggles the profiling window, which displays:
- List of frames that received events
- The specific events triggered
- Total and average execution times
Searching: Use the search boxes at the bottom of the profiling window to filter by frame name or event name (partial matches allowed).
Minimap Button: Acts as a reminder that OnEventWatch is active and allows toggling the profiling window without typing commands. To remove the button: Delete the MyMinimapButton.lua file.
Shift+Click on Events: When the ChatFrameEditBox is open, shift+clicking an event inserts its stats into the chat box for easy copying or comparison.
